Abstract (en)

Superconductive thin layer of YBa2Cu3O7- delta in which reactions with the substrate are prevented in that at least the surface of the substrate consists of a compound having such a composition that in the Y2O3-BaO-CuO phase diagram it is situated on a segregation line with YBa2Cu3O7- delta .
